Accel/Decel
Standard acceleration and deceleration is
linear. The inverter CPU can also
calculate an S-curve acceleration or
deceleration curve as shown. This profile
is useful for favoring the load
characteristics in particular applications.
Curve settings for acceleration and
deceleration are independently selected.
To enable the S-curve, use function
A097
(acceleration) and
A098
(deceleration).
